Dimers, structurally representative of those formed during thermal‐oxidative reactions in fats and oils, including the dihydroxy, tetrahydroxy, and the diketo dimer of methyl stearate, were synthesized to be used as standards and model compounds for the development of various Chromatographic methods needed for further studies. The mass spectra of both the methyl ester and trimethylsiloxy derivative of the synthetic dimeric compounds were investigated in order to facilitate development of methodology for the separation and structural determination of similar polar dimer structures isolated from actual oxidized or “abused” oil samples.
